A cultivator blade contains a tip, two wings with edges, arranged symmetrically, and a shank. On the upper surface of the tip and the wings of the blade, faceplates, shaped as triangles, are arranged with tops thereof towards the tip of the blade. The axis of the central faceplate coincides with the axis of the blade, and the axes of the faceplates of the wings are in parallel to the lines of edges thereof.
